Shadow Cruiser Campers Anybody heard anything about them?

My advice regarding old out of production campers is as always: If it is in good shape and well maintained, what does it matter what the camper is made from or what the reputation of the company is/was? You'll be on your own for repairs regardless, so you can do whatever you want if and when it comes time. Maintain the camper well and do not abuse it, and it will serve you well for many years to come.
